As you can see in the new version : the hips are rotating, giving a better and more realistic aspect to the characteralso added some others things but yeah that sums up the whole thingI Also rendered a view of the back...to see dat walking butt (YEAHH )

While I enjoy this, there are some things, and I have a keen eye for animation.

A significant suggestion would be to (adding some work here) Giving the knees a bit of lift with each step. It simply looks like she is sliding, and while it is beautiful already there is a lack of actual movement.

My next suggestion would be adding a bit of a pause between each step.

Barely a second, perhaps a quarter of one.

Also, with the raising of her torso, I do know it is an attempt to get the bounce of the breasts, but I would suggest giving the foot a grounding place. While you don't need to show us the feet, the lifting of the legs would give a bit of an up down motion. Try walking, yourself, and pay attention to the motion, and you will understand what I am saying.
